What are the different types of sun rays?
The Sun emits light over a broad range of the electromagnetic spectrum, but it is strongest (from its outer regions that we can see, anyway) in the middle of the “visible light” portion. The Sun’s rays also contain strong ultraviolet and infrared components, with some x-rays, microwaves, radio waves, etc.Of course deep inside the Sun (the core) are vastly higher-energy environments more dominated by gamma rays, too; those rays — parcels of energy — tend to be re-absorbed and re-emitted over and over on their way from the core to the surface, frequently stepping down in re-emitted energies, until the “surface” is dominated by visible light emission.If you split up just the visible-light portion of the Sun’s rays into its component colors, you can get a nifty image like the following:APOD: 2000 August 15The narrow dark bands in that rainbow that seem at first to be “missing” are not, really, but instead demonstrate that the “surface” (photosphere) of the Sun that we see most readily from the outside is not actually its outermost layer. Between the photosphere and Earth (and our eyes) is a cooler layer of gaseous material that re-absorbes specific components of the light being emitted from underneath. The placement (color) and strength of these “dark” absorption features is actually a kind of unique “fingerprint” for the Sun’s chemical composition.In other words, while a lot of stars out there may have very similar overall colors to our Sun, if you were ever lost in deep space, you might still be able to find your way home by scanning around for that one little yellow-white star with exactly that elemental make-up — with a visual-spectrum fingerprint image that matches (the APoD link, above).
Would the light emitted by the sun be a different color if it was a different type of star?
For example, if our earth was orbiting a red dwarf, would daylight be red? If it was a blue giant would daylight be blue? Assuming we were orbiting in the habitable zone around these different stars.
What colors of suns are there? how different sun color change planets in their solar system?
Well, we have blue giants which are the hottest type (all 3 of the stars/suns in Orion's Belt are blue giants). You have blue/white. White. Yellow/white. Yellow. Orange. Red. Reg/magenta (which is a borderline "brown dwarf") and if you want to include brown dwarfs themselves, you also have magenta, which is a redish color nearing brown. As you can see, some stars are classified using a mix of two colors. As for their effects on planets, color is an indication of temperature. Blue are the hottest types with each color from there down to magenta, respectively, being cooler. Obviously, the hotter the sun the farther away a planet must be to maintain a certain temperature. Size is also relative to color (as far as main sequence stars go, anyway), with blue being the largest and red/magenta/brown the smallest. Red giants are larger than orange and yellow suns, but only because they are beginning to swell and die, which is a stage that occurs after main sequence ends. Our sun, for example, will eventually end it's life as a yellow/white sun and swell into a red giant. Even though it's temperature will drop in the process, it will grow in size to a point where it will eventually boil or even consume the Earth.
WHAT IS THE COLOR, SIZE AND TYPE OF STAR IS OUR SUN?
That's better. color- white to yellow size- diameter 1,392,000 km or 864,949 miles type- G2V future processes- Red Giant, White Dwarf, Black Dwarf
Which color would the sky be if the Earth was orbiting different kinds and colors of stars?
Logically , my views would be :-The first thing is that stars don't effect the color of the sky. Secondly even though there were stars of different colours that you thought of, the sun 's light would be much brighter than that of the stars at day time which would make the stars invisible.As an artist my views would be :-At the night time the situation could be quite beautiful since there's no sun to block the stars' light at all. So the sky would look like ::::::: DISCO LIGHTS::::::: !!!!The whole world would become a dance floor which would just get us mesmerised with the colourful night show. You could imagine yourself in a disc enjoying the craziness of dico lights. These are my views and many of you could have other imaginations!
What is the real color of our Sun?
The Sun's colour temperature is green, by which is meant that the solar spectrum peaks in the green. In other words, the sun emits more green than any other color. See here: http://www.lasermax.com/downloads/Sun_co... When sun light enters the atmosphere a large part of the blue component is Rayleigh scattered. This means 1) the sky seems blue 2) the peak wavelength shifts towards the yellow. But... the difference in intensity between the blue and red parts and the green parts of the sunlight is only a factor of three or so. Our eyes are sensitive to all the colours of the rainbow, and are not very good in seeing that difference in intensity. This is so because in bright sunlight, our three colour senses are all overloaded, they all say maximum light! So our brain gets equal signals for blue, green and red and interprets this as white light. Conclusion: the sun peaks in the green, but our brain tells us it's white.
What color is the sun?
if you look right at it it is white (don't do that though because you may go blind)
What color is the sun?
Almost all photos of the sun are captured through some kind of filter or another. You seldom ever get a true color picture of the sun, and if you do get a true color picture of the sun...it isn't very interesting. Even Earth's atmosphere is effectively an optical filter...so even looking at the sun with the unaided eye (CAUTION CAUTION CAUTION...look away in less than a second!)...you still get a color filtered image. You often see red or orange photos of the sun, because they are focusing on showing the dominant hydrogen or helium absorption line (the two most abundant elements on the sun). The photos of the sun taken with either of those filters in general seem to be the most interesting, and hence why they are published the most often. If you look at the sun by unaided eye here on Earth (again...CAUTION!)...you tend to see a yellow color for the direct sun image if you look at it midday, or you see a red-orange direct sun image if you look at sunset or sunrise. This is all due to the phenomena of Raleigh scattering. But, if you look away from the sun, which you should be doing...during the day, you don't see a black background of a lack of light from elsewhere in the cosmos (like you see in the Apollo photographs). You see a pretty blue sky. That blue light of the background sky is all that has been filtered by the atmosphere...scattered. If you do an optical superposition of the blue sky and the yellow-ish direct sun image...you should get about the whitest color you can ever call white. The sun intrinsically *IS* white. The sun DEFINES white for our eyes. Our eyes evolved based upon the most abundant source of light on this planet, i.e. the sun. The most abundant emission of the sun is green light. Nearly equal intensities of colors on both sides of green occur in the solar visible spectrum...and hence the sun "should be" white. The sun is only said to be a yellow-type star (G2V in spectral class)...because all sun-like stars seem to be a little yellow when viewed from the surface of the Earth (even though a sun-like star is itself intrinsically white). A star needs to be quite a bit hotter than the sun, perhaps about a hundred or two hundred Kelvin hotter, in order to actually register as a perfect white when its through-the atmosphere image is analysed.
